Here’s something fascinating: a group of sea lions, like the one in the Whales as Individuals photo seen above, is actually called by different names depending on where they are. On land, this group is called a “colony,” but here at sea, they become a “raft!” (In mating seasons, they become a “rookery,” or a “harem” if there are many females to one male.)

This raft, as we now know to call them, is having a close encounter with a whale fluke, and the combination makes for quite the sight!
